Buy now, pay later: fees and fine print compared

Buy now, pay later (BNPL) splits a purchase into smaller payments, often four payments over six weeks with no interest. The catch is in late fees, interest on longer plans, and whether missed payments can hurt your credit. Here's what each provider's own page says.

FAQ

Does buy now, pay later affect my credit?

It can. Providers may run a soft check to approve you, and some report payments or missed payments to credit bureaus. Check each provider's terms.

What happens if I miss a BNPL payment?

Many providers charge a late fee (Klarna says up to $7, capped at 25% of the order) and may pause your account.

Estimates, not financial advice. Taxes, insurance, PMI and fees vary by lender, county and city; confirm with your lender, dealer and state agency before acting.
